Abstract
The aim of this study was to compare the effectiveness of emotional self-efficacy therapy and time perspective therapy on self-concealment and post-traumatic growth in women with breast cancer. This research employed a quasi-experimental design with a pre-test-post-test framework, including two experimental groups and one control group. The statistical population consisted of all women with breast cancer referred to cancer diagnosis and treatment centers in Tehran during the first quarter of 2025. From this population, 45 individuals were selected through purposive sampling and were randomly assigned to three equal groups (n=15 each): emotional self-efficacy therapy, time perspective therapy, and a control group. The emotional self-efficacy intervention was conducted in eight 90-minute group sessions, and the time perspective therapy intervention was conducted in six 90-minute group sessions, while the control group was placed on a waiting list. Research instruments included the Self-Concealment Scale (SCS) by Larson and Chastain (1990) and the Post-Traumatic Growth Inventory (PTGI) by Tedeschi and Calhoun (1996).
